Born to a mother from Buenos Aires and a father from Tucumán, Santiago Manuel Arias was born on May 4th 1988 in San Salvador de Jujuy and raised in Tilcara, a village in the Quebrada de Humahuaca, on the northern edge of Argentina. There, he first became familiar with music by playing the bombo legüero (drum) and later, the guitar, with the instruction of his parents.
He studied the piano for a period of his childhood, then electric bass, and later he would get started on the bandoneón with Juan Carlos Marín, in the province of Salta.
He left Jujuy at 18 years old and settled in Buenos Aires to undertake academic studies in the Manuel De Falla conservatory, later dropping out in his 4th year to continue to study independently and with private teachers.
He studied with Dino Saluzzi, César Franov, Juan Carlos "Mono" Fontana, Diego Schissi and Frido Ter Beek (Netherlands).

In 2015, again with the 2nd place of the FONDO NACIONAL DE LAS ARTES-2015, he edited the album "CRIOLLO" of the Dúo Arias Castro duet (along with Sebastián Castro on guitar).
